TLC were special guests on the 21st season of ‘American Idol‘ finale tonight (May 21) which aired on ABC.

T-Boz and Chilli took to the stage with contestant Lucy Love to perform a phenomenal live medley of their biggest hits. Chilli and T-Boz opened the performance carefully breaking down the lyrics of the smash, “No Scrubs“, to Lucy Love, before they collectively performed the anthem together.

The ladies seamlessly transitioned the performance to their first Billboard number one single, “Creep“, complete with horns and a live band.

With the audience roaring excitedly for more, including the judges Lionel Richie, Luke Bryan and their friend Katy Perry, the ladies performed the anthem, “Waterfalls“, along with Lucy Love showcasing her vocal talents as they harmonized together.

Lucy Love made it into the top 12 and was hoping to earn her spot into the top 10. With a talent like that she is destined to have a very successful career in the music business.

The ‘American Idol’ appearance marked the first time TLC performed on the show since 2011, when they performed with Lil’ Jon and the top 13 girls that year.

Tonight’s performance served as a tour sampler for their upcoming North American “Hot Summer Nights” tour, which kicks off in June, along with Shaggy, En Vogue and Sean Kingston.

Tickets for the “Hot Summer Nights” tour are on sale now.

TLC Forever” premieres on Lifetime and A&E on June 3 at 7/8c.
